This is not a Jess problem.
Using reals for non-atomic monetary units (e.g., dollar, euro, pound) is
a no-no. Absolutely. Don't do it.
You might turn to integers representing the subunit (e.g., cent or penny
or whatever). Or use java.math.BigDecimal.
Kind regards

Hi,
We are calculating some pricing information based on Jess rules and some
times the results are little fuzzy!
e.g.
(- 1.1 0.9) ==> 0.20000000000000007
(- 1.1 0.7) ==> 0.40000000000000013
Any idea what the reason is or how can I fix it other than to round-off in
the application.
I have tested the issue with Jess versions 70p2 as well as 71b1
Thanks.
